The second strategy, ResNet-50-S3-SR, is based on the former, adding the activation function, i.e., ReLu [1]}, to each layer of the shared two-layer MLP as shown below:
\(\begin{array}{l}confidence= \\Softmax\left(\sigma \left(W_2\left(\sigma \left(W_1\left(lc\right)\right)\right)\right) \times \sigma \left(W_2\left(\sigma \left(W_1\left(gc\right)\right)\right)\right)\right)\end{array}\)
